yep, stands for Pennsylvania Wrestling Association, my cousin made that back in the day and we just stuck with it, We are located in Chambersburg,PA. That ring was made out of alot of stuff, we used a trampoline for a base to start, Tires underneath it so it didnt have to much bounce, Plywood nailed together on top and a thin layer of padding, which ended up getting ripped off, We are going to be building another ring soon, But wont be as tall,single layer of tires, and a wooden platform with ladders as corners staked into the ground, i can get pics up as soon as its done if anyone is interested
